Feature for Today
Thumbnail of Stephen McCormick

Stephen McCormick died on 28 Aug 1839, today, a second chance to familiarize yourself with his contribution to agriculture. (He was born on 26 Aug 1784.)

He was an American inventor and manufacturer of a practical cast iron plow with detachable components. His early achievement, while a youth, was to increase the productivity of a water-powered grist-mill by improving the shape of its nether millstone (the lower of the two millstones) used to grind flour. Though his father desired that he should make law his profession, he flatly refused. He was more interested by invention. By 1816, he had invented a cast-iron plough superior to Charles Newbold's earlier design. McCormick's first of several patents was issued on on 3 Feb 1819. His cast-iron mould board had an adjustable wrought-iron point mounted beneath, able to decrease the draft, while deepening the furrow, and breaking up the soil more effectively. Standardization of the replaceable parts led to the development of improved manufacturing processes.

For a larger picture of McCormick with one of his plows, and a few more biographical remarks, read this article on Stephen McCormick.


Book of the Day

George Hoyt Whipple, born 28 Aug 1878, was an American physician and pathologist who shared the 1934 Nobel Prize for Physiology or Medicine with George R. Minot and William P. Murphy for “their discoveries of a treatment of pernicious anemia with a special diet of liver.” Whipple began a study in 1920 of the influence of food on blood regeneration. From experiments on dogs bled to reduce blood volume, he found the best food to stimulate the bone marrow for the production of the new red blood corpuscles was raw liver. Other foods, including kidney and apricots were also found helpful. Minot and Murphy applied Whipple's discovery of the value of liver. They designed a special diet for humans with a particular noninfectious disease - pernicious anemia. The three researchers made a major advance with a non-drug treatment of this condition. Today's book pick is: , by , which will give you some idea of what goes in to winning a Nobel Prize!
